He did a lot of dangerous jobs for lower pay in Korea. Since he was an illegal foreigner with no id and he kept his mouth shut about everything except that tyr is his daughter. I haven't completely read the novel yet but someone here spoiled that he gut stuck in some kind of freezer room or container idk. No one noticed he was stuck and he died.
It really broke my heart, he even did jobs like cleaning the sewer for free so he can get more jobs. He also got scammed a lot because he knew nothing about this world. Just imagine how hard it must be for his to raise a newborn baby in those conditions. If it wasn't for the grandma in room 107, their life would've been much harder. She was the one who helped his rent a room in her apartment building and even find him jobs. What use is his magic and sword skill? That isn't going to fill his stomach or put a roof over his head. If he even let his magic power known then he would be treated as some kind of monster. They really suffered a lot.
Hope for what. That he was actually alive? No he really died, in a way that he didn't deserve. Imagine him slowly freezing to death in that room, with no one to hear his scream, thinking about his young daughter who would be left all alone. When grandma got the news of his death, he was already cremated as an unidentified dead body. So they could only retrieve his few belongings and an urn with his ashes.
He worked from early morning to late at night, barely slept a few hours but even with more than 18 hours of work, the money he earned was measly. Not to mention at first a lot of his employers didn't pay him at all for his work or paid him less than he was supposed to get. He knew finding any decent work was impossible without any id so he really did all kinds of job. The youngest son of the lumien family, 2nd only to the royals in authority, was cleaning gutters for free. Yk where they step into large sewer pipes to pick objects that might block the flow of sewer water by hand. He worked so hard that he barely had time to spend with tyr.

Someone PLEASE spoil me, we know who her father is, that's why I can't believe that he died so easily in our world, please please can someone spoil me about what we're gonna discover abt that ? (/TДT)/
